A black hole is a region of spacetimeexhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is possible is called the event horizon. Although the event horizon has an enormous effect on the fate and circumstances of an object crossing it, no locally detectable features appear to be observed. In many ways a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is on the order of billionths of a kelvin for black holes of stellar mass, making it essentially impossible to observe.

Objects whose gravitational fields are too strong for light to escape were first considered in the 18th century by John Michell and Pierre-Simon Laplace. The first modern solution of general relativity that would characterize a black hole was found by Karl Schwarzschild in 1916, although its interpretation as a region of space from which nothing can escape was first published by David Finkelstein in 1958.

Uranus (from the Latin name Ūranus for the Greek god Οὐρανός) is the seventh planetfrom the Sun. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Uranus is similar in composition to Neptune, and both have bulk chemical compositions which differ from that of the larger gas giants Jupiter and Saturn. For this reason, scientists often classify Uranus and Neptune as "ice giants" to distinguish them from the gas giants. Uranus' atmosphere is similar to Jupiter's and Saturn's in its primary composition of hydrogen and helium, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. It is the coldest planetary atmosphere in the Solar System, with a minimum temperature of 49 K (−224 °C; −371 °F), and has a complex, layered cloud structure with water thought to make up the lowest clouds and methane the uppermost layer of clouds. The interior of Uranus is mainly composed of ices and rock.

Delta IV is an expandable launch system within the Delta rocket family, comprised of both medium & heavy-lift rockets.🚀The rocket in this animation is the Medium+ (5,4), which is one of other versions from the Delta rocket series. Its main constituents are designed by Boeing’s Defense, Space & Security Division. They are all built in the United Alliance's facility located in Alabama🇺🇸

The purpose of the rocket’s construction was to support the civil and military ⚔️payloads of the US government. The Delta IV was designed in order to serve the US Air Force's ✈️Evolved Expendable Launch Vehicle (EELV) program- just like the Atlas V rocket.🚀It's first launch was in 2002 and has flown many successful missions since then.🌍

Cool Facts About Delta IV Medium+ (5,4)
-This rocket has 4 solid rocket boosters, which provide extra thrust after liftoff🔥
-There is a larger Upper stage(5 meters across), which gives the rocket the ability to re-ignite💥
-A payload fairing also 5 meters in diameter is also used in order for the rocket to accommodate large amounts of Payload🤩

This iconic photo is of Astronaut Edward Fincke👨🏼‍🚀on the third out of four scheduled spacewalks back in 2004 on the Expedition 9 International Space Station mission. The stunning view of a cloudy earth lingers in the background🌎✨Astronaut Fincke was a flight engineer and science officer on this mission; and in this image he is seen wearing a Russian Orlan spacesuit.🇷🇺

On this spacewalk Astronaut Edward Fincke and partner, Cosmonaut Gennady Padalka spent 4.5 hours performing Extravehicular activities. They were tasked with exchanging experiments, as well as with the installation of hardware⛓that would later on assist in the operation of a device known as Automated Transfer Vehicle (AVT).📡
———————————————————
What is He Up To Now?
———————————————————
Astronaut Edward Fincke will be one of three other astronauts to fly aboard the very first manned Starliner Space capsule flight up to the ISS! 🛰(Hopefully later on this year). This spacecraft along with Crew Dragon will mark the beginning of the US’s endeavor to start and continue to launch humans from American Soil by American designed and built spacecraft! 🚀🇺🇸

🌌Over time, our universe will seem to get smaller and smaller, because it’s getting bigger and bigger so fast.
.
🌌And that is thanks to the Big Bang.
.
🌌Because at the beginning of time, a tiny point in space the size of an apple expanded 90 billion light years in width in just a single second.
.
🌌That is incomprehensible. And these crazy scientists are now debating what happened before and what will happen after the Big Bang.
.
🌌Some speculate that the universe will just continue to expand forever. They call this the Big Rip. Eventually causing every single atom in the universe to rip apart ending the entire universe.
.
🌌But some also speculate that after trillions of years, gravity will slowly attract everything back to a single point again. Causing a new Big Bang.
.
🌌They call this the Big Crunch. Which is basically an infinite cycle of expansion and contraption. Where the Big Bang has already happened an infinite amount of times before.
.
🌌Now if this is true, then I wonder if this cycle repeats in the exact same way every single time. Meaning that our lives have already been played out in the exact same way an infinite amount of times.
.
🌌Or perhaps there’s some randomness to it and  many alien civilisations have trived in the past but where unable to survive the Big Crunch.
.
🌌Fascinating stuff!
.
🌌What are your thoughts on this tho?

At its peak, the plasma rises to heights that are several times the diameter of Earth! #space #universe

We use the Solar Dynamics Observatory, which captured this view, to better understand the Sun's influence on Earth and near-Earth space by studying the solar atmosphere in many wavelengths simultaneously. This allows us to better understand the solar variations that influence life on Earth and humanity's technological systems by looking for the solar wind, energetic particles, and variations in the solar irradiance that lead to better predictions of space weather events!

For the first time, scientists have directly detected gravitational waves – ripples in space-time – in addition to light from the spectacular collision of two neutron stars. This marks the first time that a cosmic event has been viewed in both gravitational waves and light.

📸 HiRISE camera aboard NASA's Mars Reconnaissance Orbiter captured this closeup image of a fresh impact crater near the Sirenum Fossae region of Mars! 😱 #Mars #space #universe
•
This impact crater appears relatively recent as it has a sharp rim and well-preserved ejecta, the material thrown out of the crater when a meteorite hit Mars. 💥 The steep inner slopes are carved by gullies and include possible recurring slope lineae on the equator-facing slopes. RSL could be a sign that water, its freezing point lowered by a high concentration of salt, could be seeping down these steep slopes. Fresh craters often have steep, active slopes, so the HiRISE team is monitoring this crater for changes over time. The bedrock lithology is also diverse. The crater is a little more than 1-kilometer wide! 🛰

A dying red giant star losing mass! 💥
These compilation of images, obtained with the Advanced Camera for Surveys on @nasahubble view of the expanding halo of light around distant star, named V838 Monocerotis. #hubbletelescope #space #universe
•
V838 Monocerotis is located about 20,000 light-years away from Earth in the direction of the constellation Monoceros, placing the star at the outer edge of our Milky Way galaxy! 🔭
The effect, called a light echo, unveiled never-before-seen dust patterns when the star suddenly brightened for several weeks in early 2002. A light echo is light from a stellar explosion echoing off dust surrounding the star that produces enough energy in a brief flash to illuminate surrounding dust! The star presumably ejected the illuminated dust shells in previous outbursts. Light from the latest outburst travels to the dust and then is reflected to Earth. 🚀
